Abstract:An antenna system, similar to the four-element array described in Safety and Planning Division Report No. 5, except operating above a wire mesh counterpoise, was installed and tested at the Bowie, m-2 light beacon. Improvements in the method of conducting energy from the transmitter to the antenna were incorporated in this installation. The system was found to produce patterns equivalent to those measured for the former antenna and to be relatively free of variations caused by snow, sleet, or growth of vegetation.
